Starlight BIlly in Zenless Zone Zero

Billy is getting a massive upgrade in the upcoming version of the game, and before you dump all your batteries into random materials, here is what really matters.

Below is the complete material breakdown to take Starlight Billy to level 60, max all of his skills, and fully upgrade his signature W-Engine.

Total Materials to Fully Max Starlight Billy (Level + All Skills)

First, we got an overview of how much you need in total if you want to max out Starlight Billy’s Agent level and all his skills. To completely build him, you will need the following materials:

MaterialAmount
Basic Physical Chip25
Advanced Physical Chip75
Specialized Physical Chip250
Basic Rupture Certification Seal4
Advanced Rupture Certification Seal32
Arbiter Certification Seal30
Unknown Boss9
Unknown Boss60
Hamster Cage Pass5
Senior Investigator Log300
Denny3,705,000

Keep in mind that the boss materials needed for Starlight Billy are still unknown. You can try and pre-farm the latest available boss if you want, but chances are new ones will release by the time the Agent comes out.

Starlight Billy Promotion Materials (Level 0-60)

If you only want to promote Starlight Billy to level 60, you will need:

  • Basic Rupture Certification Seal ×4
  • Advanced Rupture Certification Seal ×32
  • Arbiter Certification Seal ×30
  • Denny ×800,000

This covers ascension only. It does not include skill upgrades. Compared to skill materials, promotion is relatively manageable.

Starlight Billy Skill Materials (All Skills to Max)

If you already have enough materials for his Ascension, but you do not know what you need to max out his skills, here is what you can farm:

MaterialAmount
Basic Physical Chip25
Advanced Physical Chip75
Specialized Physical Chip250
Unknown Boss9
Unknown Boss60
Hamster Cage Pass5
Denny2,905,000

This is where you will need the most resources. Skill upgrades account for nearly 3 million Denny on their own, and you will require specific Boss materials. We will update the table once the Boss Materials are known.

Keep in mind that a full investment makes sense only if you are committed long-term to the character.

Starlight Billy Signature W-Engine Materials (0-60)

If you plan to pull Starlight Billy’s signature W-Engine, you will also need:

  • Rupture Component ×4
  • Reinforced Rupture Component ×32
  • Specialized Rupture Component ×30
  • W-Engine Energy Module ×200
  • Denny ×400,000

It is a good idea to pre-farm the materials for Starlight Billy’s signature weapon as well, if you plan on getting both the agent and their weapon. This way, you can directly head into battle with them!

Smart Pre-Farm Strategy

If you are unsure about pulling Starlight Billy, you can always focus on farming universal resources first:

  • Dennies are always needed
  • Farm Senior Investigator Logs
  • Secure weekly time-gated materials when possible
  • Start farming the Physical Chips

You will always need those, no matter who you pull for, so if you are not sure about Starlight Billy, you can always farm for general materials that you know you will eventually need either way.

The 250 Specialized Physical Chips are the biggest grind. These are safe to farm now and almost guaranteed to remain relevant. Skill materials are usually the longest farm, so starting here gives you the most value.

Planning ahead can definitely be the difference between a day-one max build and weeks of delayed progression, so if you want to go for all Starlight Billy and his super cool Bike, you better start preparing now!
